i saw a girl enter the house of the guy i was involved with, i txted him later on saying who is the girl i saw go in? i got a txt later saying that its a girl named jessica....at first i was like is she a new girl? that happened a while back. i never found out who she was. i know what she looks like. today i went on facebook and i didnt know the guy i was with had a facebook till i serached him up and i found him. i looked at all his stuff on facebook, and there was a girl who posted alot of things about shows like for 21 and over. she posted alot, and her name was jessica. i was like wait..... wasnt that the name of the girl who txted me...... then i serached his friends i serched for jessica to see if he had more, but that was the only jessica she was a diffrent raise than him and the girl i saw go in his house..... i looked and found nothing weird except the girl posting things about girls and shows.... what does this mean. especially since the jessica who txteed me looked nothing like the girl on facebook? what could it mean?
